Scs-Winter Creek Site-18 dam
Scs-Winter Creek Site-18
SCS-Winter Creek Site-18 is a state-regulated dam located in Grady County, Oklahoma, specifically in the city of Bradley. Built in 1966 by the USDA NRCS, this earth dam stands at a height of 39 feet and serves the primary purpose of flood risk reduction along Laflin Creek. With a normal storage capacity of 145 acre-feet and a maximum storage of 1145 acre-feet, this dam plays a crucial role in managing water resources in the area.
The dam features a controlled spillway with a width of 1 foot and an outlet gate consisting of one valve. Despite being assessed as low hazard potential and not rated in terms of condition, the risk assessment for SCS-Winter Creek Site-18 indicates a very high risk level. The dam has not been modified since its completion and has only undergone inspections every 5 years, with the last inspection dating back to 1980. With the state regulatory agency OWRB overseeing permitting, inspection, and enforcement, this dam remains a key infrastructure for mitigating flood risks in the region.
Overall, SCS-Winter Creek Site-18 stands as a critical structure for flood risk reduction in Grady County, Oklahoma. Managed by the state and constructed by USDA NRCS, this dam plays a vital role in protecting the surrounding areas from potential flooding events along Laflin Creek. Despite its age and limited recent inspections, the dam's low hazard potential and controlled spillway design highlight its importance in water resource management and climate resilience efforts in the region.
Dam data reference
Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About Scs-Winter Creek Site-18
Where does the data for Scs-Winter Creek Site-18 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
